Finn's Take· TL;DROn any given day at an Idaho hospital, half the newborns Dr. Tom Patterson sees don't get vitamin K shots that have been given to babies for decades to prevent potentially deadly bleeding . "When you look at a child who's innocent and vulnerable — and a simple intervention that's been done since 1961 is refused — knowing that baby's going out into the world is super worrisome to me," said Patterson, who's been a pediatrician for nearly three decades .
This isn't an isolated incident. Doctors across the nation are alarmed that skepticism fueled by rising anti-science sentiment and medical mistrust is increasingly reaching beyond vaccines to other safe and routine care for babies . A recent study in the Journal of the American Medical Association, which analyzed more than 5 million births nationwide, found that refusals of vitamin K shots nearly doubled between 2017 and 2024, from 2.9% to 5.2% .
The rejection of vitamin K isn't happening in isolation. Other research suggests that parents who decline vitamin K shots are much more likely to refuse getting their newborns the hepatitis B vaccine and an eye ointment to prevent potentially blinding infections . Rates for that vaccination at birth dropped in recent years, and doctors confirm that more parents are refusing the eye medication .
Parents give many reasons for turning down preventive measures, like fearing they might cause problems and not wanting newborns to feel pain . "Some will just say they want more of a natural birth philosophy," said Dr. Steven Abelowitz, founder of Ocean Pediatrics in Orange County, California . "Then there's a ton of misinformation. There are outside influences, friends, celebrities, nonprofessionals and political agendas."
"There's more mistrust from the conservative side, but there's plenty on the more liberal side as well," he said, "It's across-the-board mistrust." Social media provides ample fuel, spreading myths and pushing unregulated vitamin K drops that doctors warn babies can't absorb well .
"Vitamin K is important for helping the blood clot and preventing dangerous bleeding in babies, like bleeding into the brain," said Dr. Kristan Scott of the Children's Hospital of Philadelphia, lead author of the JAMA study . Before injections became routine, up to about 1 in 60 babies suffered vitamin K deficiency bleeding, which can also affect the gastrointestinal tract . Today the condition is rare, but research shows that newborns who don't get a vitamin K shot are 81 times more likely to develop severe bleeding than those who do .
The human cost is devastating. "I cared for a toddler whose parents had chosen that risk," the Seattle doctor said. The child essentially had a stroke as a newborn and wound up with severe developmental delays and ongoing seizures . At a February meeting of the Idaho chapter of the American Academy of Pediatrics, doctors said they knew of eight deaths from vitamin K deficiency bleeding in the state over the preceding 13 months .
Despite the tensions, doctors remain committed to dialogue. "I do think these families care deeply about their infants," said Dr. Kelly Wade, a Philadelphia neonatologist . In Idaho, Patterson sometimes finds himself clearing up misconceptions. Some parents will agree to a vitamin K shot when they find out it's not a vaccine, for example .
The challenge ahead involves rebuilding trust while protecting vulnerable newborns. As medical misinformation continues spreading through social media and political channels, healthcare providers must navigate increasingly complex conversations about treatments that were once routine. The stakes couldn't be higher — every declined intervention represents a potential tragedy that established medicine has worked decades to prevent.
